Description
Technical field
The present invention relates to a kind of modification method that prints colour.
Background technology
Color theory be in the teaching textbook of general primary school degree all one by one solution say clearly.The color annulus is that the educational aid of commonly using is familiar with color theory.Particularly, natural chromatogram can be by pinkish red (M), red (R), yellow (Y), green (G), blue or green (C), blue (B) six look combinations.Pinkish red, yellow, blue or green main primary colors is to form by subtractive process, is applicable to the use of the products such as all kinds of colors of ink, paint; Red, green, blue secondary primary colors is to form by additive process, is applicable to electron-optical and is applied on the products such as TV, scanner.
According to above color theory, scientist utilizes filter glass according to subtractive process, analyzes that main primary colors is pinkish red, yellow, blue or green three looks, adds that then black is the image intensive as four-color process fabrication techniques basis in the future, until today.
The Traditional Man image color segmentation needs the height professional technique.Utilize setpoint color optical mirror slip as optical filter, by full-colour image, to be parsed into magenta, Huang and three blue or green main primary colors.And traditional printing industry just utilizes the pigment of three main primary colors separately to add black to be combined into printed matter, the emulation full-colour image, only in thin color gamut space running.
Along with computer technology and sustainable development, press has been applied high-speed computer and has been calculated the work energy, and data store quick and the color separation of Application Optics electronic digital, does not need staff to make.Many colors color separation energy supply, the birth of electronics filter, as long as accurately the look pollakicoprosis of the required primary colors of input can.Color selects to exceed the scope of traditional C MY master primary colors section, so digital printing device can select nearly 12 primary colors and time primary colors to simulate the euchroic print image for visual viewing and admiring.This many colors color separation energy supply also can be given the use of " high-fidelity " printing.Based on " high-fidelity " printing, can compensate CMY master's primary colors and lack, so in press add the red, green, blue of accurate secondary primary colors; Or three primary colors are blue or green+red, yellow+green, pinkish red+blue etc. or select wherein 2 groups, 3 groups etc., the result of image can be more truer than single colour gamut that adopts main primary colors district CMY to form, can reach to panchromatic true border as simulate effect, with us, see every day and watch the same, " high-fidelity " printing technology is exactly that current euchroic is drilled the tidemark of translating.
In print production, can really drill the panchromatic effect of translating on light source, can adopt euchroic secondary and three primary colors production, based on RGB, be secondary primary colors and for example, from the combination of two main primary colors: red=yellow+pinkish red (R=Y+M), green=blue or green+yellow (G=C+Y) with and blue=pinkish red+blue or green (B=M+C).Traditional secondary and three primary colors are analog generation, as utilize spectroscopic data and produce accurate secondary and three primary colors pigment, that can greatly improve traditional printing simulation time primary colors look scarce state and copy true scenery effect, and can coordinate many color printings production decision.
Simulation euchroic secondary primary colors; The birth of three primary colors etc. is to simulate euchroic full gamut image from the main primary colors of CMY.Whenever two main primary colors wherein produce secondary primary colors RGB then after interosculating.Three primary colors are to be combined into mutually from main primary colors and secondary primary colors again; Each primary colors more four primary colors, five primary colors etc. of can being born that interosculate again, purpose is the emulation true color image.This two, three, the source of the fourth class time primary colors is all the main primary colors formed from manual manufacture pigment, as the natural spectrum of simulation, turn round and look at this and can not really drill the panchromatic effect of translating on light source.So the long-term storage of printing industry is produced in scarce look state.
What is meant by " high-fidelity ", print? the high-fidelity printing is in conjunction with the plurality of color typography, enlarges the color color gamut space, can reach the more approaching effect of true scenery colour reproduction, more perfect boundary.It is CMYK+ orange and green that press 6 looks commonly used are made; It is CMYK+RGB that 7 looks are made.
Call what press and need " high-fidelity " printing? based on traditional C MYK printing manufacturing technology, after the main primary colors colour mixture of acceptance three that have to be helpless, produce the printing boundary of narrow full gamut." high-fidelity " printing is to adopt natural pigment, and directly instruction to required primary colors in natural chromatogram replaces simulating time primary colors, and this can improve CMY master's primary colors look and lack problem, drills the best printing process of translating the picture simulation of the true border of euchroic, for all kinds of print production schemes.
Although polychrome is counted color separation technology and existed, but press does not have a look keyholed back plate reason method of effectively using in high-speed production, and the operator has each colo(u)r specification non-equilibrium state of difficult visualization, effectively reaches and regulates and controls exactly colo(u)r specification to make in real time fast.Traditional CMYK electronics metering equipment can not effectively be differentiated time unbalanced production of primary colors colo(u)r specification.
